ABSTRACT:
Apparatus for sealing the periphery of an opening such, for example, as an opening through which bulk material is fed into a bin, a shaft opening through which hot bulk material is cooled, or an opening in a blast furnace shaft, of the type wherein a channel extends around the periphery of the opening into which a dividing wall extends whose lower end is spaced from the channel bottom so as to define a pair of adjacent channel portions which intercommunicate through the space between the lower end of the dividing wall and the channel bottom so that liquid provided in the channel at least fills the communicating space. According to the invention, a pair of external channels are provided, each of which is adjacent to and extends around one of the inner and outer sides of the peripherally extending channel, respectively, so that the latter comprises an inner channel. A liquid inlet communicates with the inner channel so that liquid continuously supplied into the inner channel will continuously overflow over at least one of the walls which separates the inner channel from one of the outer channels so that the liquid can be removed from the external channel into which the liquid overflows through outlet means.
